Hi this is the start of my Blog for the 2014 mini Se7en S Class championship with my little 1275cc mini built to MSA safety regulations and mini 7 championship regs,

This is probable the cheapest form of mini circuit racing around with the mini's around 5k and race entry fees of £350 for double headers

The mini runs on dunlop 10" slicks that that have a lot more movement than the dunlop slick which makes driving the mini even more exciting and challenging you'll often see us sideways!!

The championship provides in my opinion the best tin top racing in the UK with upto 30 mini's on track at once!

I've been a member of TMF for the last ten years and everyone on here keeps the passion for minis alive!! I have had my project tread of my turbo mini on here for the last few years she came from a scrapper to a circuit car, this brought me to the mini 7 racing club and my ambition to race with them.

So follow my 2014 and come and see us for a chat at the races this year help support minis in Motorsport.

I loved your turbo mini, was a beast, but racing in a championship with near identical specs is the best you can't beat it! Hopefully il see you in the paddock, I'm building a mini seven racer at the moment as well!

I'm sure the seven S class minis don't run slicks? Do they?
